## LyraElizabethAdams 3 years ago Hi, I'm having trouble understanding how they found the missing sides to this figure (it's attached). Could you help me understand why the answer is 13/2? Thanks!

Well It Most Likely Has Something To Do With Multiplcation .. How Did You Get 6.2?

I can't remember. This test is from a timed SAT test, so I just kind of rushed through it.

Ok.. So If The Area Is A Fraction Then The Perimeter Is Probably Going To Be A Fraction.

Oh, I remember . . . I assumed, that because the length of the side, that was 1, seemed longer than the piece that was missing from that same side . . . I thought that it must be less than one.

now area of big rectangle is 2*1=2

8. sumanthy

area of small rectangle you know the lenght as 1 but little height is taken as x 1*x=x now x+2=9/4

9. sumanthy

x=9/4-2=(9-8)/4 x=1/4

10. sumanthy

now perimeter is 2+1+1+1/4+1+1/4+1=6+1/2=13/2
